| 1 First dissolve KOH and K2HPO4 in water, then add uric acid and boil until the acid is dissolved. Cool medium to room temperature under 100% N2 gas atmosphere and add all other compounds, except carbonate and thioglycolate. Dispense under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave for 15 min at 121°C. Then add carbonate (filter-sterilized stock solution prepared under 80% N2 and 20% CO2 gas atmosphere) and thioglycolate (stock solution, autoclaved separately under 100% N2 gas). Adjust pH of complete medium to 7.0 - 7.5, if necessary. | |||||
